Checking the SCSI speed for RAID controllers
Check SCSI channel speed if there are issues with the hard drive. Before
shutting down and after rebooting, check the previous power up negotiated
speed using Power Console Windows Utility. If the speed shown is anything
else but Maximum or 160M or if Asynchronous displays, there is a serious
issue with the SCSI chain. This could be either a bad termination, SCSI
backplane, cable or a drive is about to fail. Additionally, you should
immediately check the media errors on the same menu. The Asynchronous
speed is usually accompanied by media errors and sense error keys in
the logs.
SCSI speed is negotiated when the system powers up. Warm Rebooting
will not trigger a re-negotiation.
Check the SCSI speed setting of 160M using the CTRL+M utility. This will
restart the system.
